Timer/Counter: Type 82C54 (3x16 bit)

I/O Connectors:

Two Industry Standard 50 pin headers

RoHS Available. Please contact us for ordering information

FLEXIBILITY

The following functions
are available in many configurations giving the user the ability
to specify exactly what’s needed. Interrupts are individually or globally enabled or
disabled via software.
A status register is provided to determine the interrupt source.

ANALOG OUTPUTS

Output ranges of 0-5V, 0-10V, ±5V and ±10V, are field selectable with jumpers. Note
that four conversions may take place at once and that, since the D/As are double buffered,
data for the next conversion may be loaded simultaneously.

COUNTER TIMERS

The circuit uses an 82C54 (3 sixteen bit counter/timers). The user has access to each
counter/timer’s gate, clock, and output signals. The output of counter two can be used to
generate an interrupt. The software package supports counting events, frequency output,
pulse and frequency measurement.

DIGITAL I/O

The circuit uses an 82C55A PPI with mode 0 supported. Ports A and B (16 lines) are
buffered and pulled up to 5V. Port C features Change of State detection.

SOFTWARE

The package includes a setup program detailing all jumper settings. Also included are IRQ drivers, samples for DOS, and utilities for Windows operating systems (XP -> 10, both 32 & 64 bit). Full register-level support for use in custom real-time or embedded operating systems.
